After the container is tilted back somewhat, a base plate is inserted and the whole ensemble is tilted back to the point where the stack stands on the horizontally positioned base plate. Then the container is removed towards the bottom.

Abstract: A Bulk Mail Container (BMC) unloader uses a simple crossed four bar-linkage to move a predetermined point on a BMC unloader in a substantially straight line while the overall BMC unloader rotates about that predetermined point so as to upend the BMC container.
